` 6 Claims. (Cl. 137-111) This invention relates to a supply fixture and a nozzle portion I1, the latter terminating in a control for toilet storage tanks.

The chief object of this invention is to provide a fixture which is adapted to supply water to such storage tank and in a manner which is of relatively silent character.

Another object of the invention is `to provide such a supply fixture which is of antisiphon character, that is, the Water in the tank cannot siphon back and commingle with the supply and thus contaminate the latter.

The chief feature of the invention consists in vproviding a water discharge whereby the water discharged therefrom is caused to plummet as a single column, without lateral dispersion or spraying, to the bottom of the tank, such column of water penetrating the water being collected by the tank and relatively noiselessly entering the collected water. This constitutes the silent feature of the invention.

Another feature of the invention is in positioning the discharge above the normal storage level and also above the overflow level so that at no time is it possible for the water in the tank to be siphoned into the supply line.

A further feature of the invention consists in providing a float operated control valve and associating therewith an adjustable throat for regulating the flow from the valve controlled chamber to the discharge device.

Other objects and features of the invention will be more particularly pointed out hereinafter.

The full nature of the invention will be understood from the accompanying drawing and th following description and claims:

In the drawing Fig. l is a front elevational view of an embodiment. of the invention associated with a portion of a tank enclosed mechanism of a toilet storage tank, a portion of the latter being shown in section.

Fig. 2 is an enlarged sectional view of the supply and control xture embodying the invention.

Fig. 3 is a top plan View thereof. y

Fig. 4 is a transverse sectional view taken on the dotted lines 4-4 of Fig. 2 and in the direction of the arrows.

In the drawing I0 indicates a toilet storage l tapered flange portion 38.

suitably formed end portion I8 which defines a dischargeypassage I9 that extends through the aforesaid and is in free communication with the riser I3.

A body portion 20'having a chamber 2| -adjacent the discharge nozzle I8 and surrounding the portion I1 has threaded connection as at 22 with the threaded portion I6. This constitutes the support for thesupply and control flX- ture. The chamber 2| communicates with a superposed lchamber 23 by means of a tapered passage 24. The upper end of the chamber 23 is closed by a plug or closure 25 having threaded engagement 26 with an upper portion of the body casting and in axial alignment with the aforesaid described parts. This closure 25 terminates at its lower end in a frusto conical, preferably complementarily formed, portion 2'I. The seat 24 and the valve portion 21 when properly spaced apart provide a conically directed channel, providing communication of regulated amount between chamber 2| and chamber 23.

The outerl end of the closure 25 integral with the control valve 2l is provided with a lateral flange 28. The'body portion includes a projecting ange 29 apertured as at 30 to receive a retaining bolt 3|, the head of which overlies the flange 28 of the valve and closure member. This member 25,-21 constitutes a closure for the chamber 23 and a valve for controlling communication, as stated, between chambers 2l and 23.

The member 25 has a bore 32 therein of cylindrical character and slidably mounted in said bore is a piston-like valve member 33 provided with a packing construction 34 for leakproof operation. The lower end of said member33 is reduced as at 35 and is threaded as at 36 to receive a threaded sleeve 3'I having an inwardly Between the lend 39 of the member 33 and this flange portion 38 is positioned a seal or valve member 40, the same being retained upon plunger 33 by means'of the flanged portion 3'I-38 and being movable with said member 33. The latter includes an upwardly directed projection 4I slotted as at42 to receive an arm 43 of a lever member`44 pivotally supported at 45 by means of the thumb screw 46 which is mounted in the spaced ears 4l integral with an upwardly and laterally directed portion 48 of the body portion 2U.

Included within said upwardly and laterally directed portion 48 is a supply passage 49 which at its lower rend communicates with chamber 23 as` shown in Fig. 2. The upwardly and laterally directed portion 48 terminates in an enlargement 50 which is chambered as at 5I and its lower end is open and internally threaded a's at 52. The passage 49 communicates with this chamber 5I.

Projecting from the enlargement 50 is a pair of ears 53 and the same pivotally support as at 54 a lever 55. This lever terminates in a threaded socket 56 adapted to receive an arm 51 in the form of a rod, or the like, that threadedly supports a float 58. The lever 55 between the connection 56 and the pivotal support 54 is connected to a. dual link structure 59 connected together as at 60. This link structure is pivotally connected to the float mechanism as at 6l and is pivotally connected as at 62 to an outer free end of the lever 44.

Extending outwardly from the chamber 50 is a tubular portion 63--see Fig. l-which supports a tube 64 that discharges into the overow pipe 65 common to all toilet storage tanks. This overow pipedischarges to the conduit 66 below the usual manual control ball valve. The conduit 66 communicates freelyv with an intake structure xture 61 normally. It is maintained in closed position by the rubber ball-like4 valve 68 carried by the lower end of the rod 69, slidably supported in the guide 'l0 adjustably supported on the overflow tube 65 as at 1I. An actuating mechanism of conventional character common to structures of this general type, includes the lifter member 12 and the head portion 13 of the rod 69 bears on the lateral portion 14 of Said lifter member. y

It will be noted that as long as water is being supplied to the chamber 23 in regulated amount by means of the adjustment previously mentioned; water will discharge into the chamber 5I and a relatively small amount of this water will discharge through tube 64 into the overflow tube 65 and thence to the line 66.

After the tank has been lled to the level indicated by the dotted line determined by float valve adjustment and the manual member is operated, the rubber ball valve 68 is elevated and the water discharges from the tank into the toilet bowl proper and ushes the bowl. In the event such flushing siphons the water out of the trap normally beyond or included in the bowl, the water discharged by line 64 into the overflow 65 upon closure of the valve 68, supplies water tothe bowl and especially the trap portion thereof to water seal the same. This prevents the venting to the bowl of the undesirable odors that might be present in the waste pipe or line from the toilet xture.

Reference now will be had more especially to Figs. 2 and 3. In the threaded portion 52 there is threaded a sleeve 10 which has a grooved periphery 1| spaced from the inside walls of the chamber 5| It also includes an exposed lateral flange 12 that -bears against the end of the chamber 5I and closes said chamber. It includes a central opening 13 which is slightly less in diameter than the diameter of the bore 14. The upper end of the tube or sleeve 10 terminates in spaced relation to the closed upper end of the chamber 5I.

As shown clearly in Fig. 4, the passage 49 discharges tangentially into the chamber 5l and by reason of this tangential discharge, the water assumes a circular path about the annular channel between the inside side wall of chamber 5I and the channel type exterior of the sleeve structure 10. The water escapes by iiowing` over the top edge of the sleeve structure 10 and passes downwardly through the bore and through the central discharge opening 13. The lower level of such opening is above the water level as` shown clearly in Fig. 1. Wherefore, .this fixture is of antisiphon character-that is, thev lwater from the bowl tank cannot be siphoned into the supply line. The aforesaid sleeve structure insures to a limited degree the plummeting action or columnizing of the water to be discharged from the illustrated in Fig. 4, the same providing a central free channel, as it were, of restricted character, and a plurality of radial channels radiating therefrom and therebetween is a plurality of channels between such fixture and the interior 14 of the bore of the sleeve member.

This fixture is retained within the bore by means of the inwardly directed flange portion 80 denlng the central opening 13. The corrugated annularly arranged insert is indicated bythe numeral 19. If desired, the insert may be of dual character as shown and each will be substantially identical and superimposed one relative t0 the other and the same may be oifset angularly, one relative to the other, to insure the proper action of this segregating or columnizing device.

While the invention has been illustrated and described in great detail in the drawing and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein as well as others which will readily suggest themselves to persons skilled in this art, all are considered to be within the b'road scope of the invention, reference being had to the appende claims.
